Electric Bed with a Lifting Adjustment Structure

Abstract

An electric bed includes a bed frame ( 23 ), a power device ( 20 ), a linkage ( 21 ), and a control device ( 22 ). The bed frame includes a head portion ( 230 ) and a leg portion ( 231 ). The power device includes a first electric cylinder ( 200 ), and a second electric cylinder ( 201 ). The first electric cylinder is mounted on the head portion of the bed frame, and the second electric cylinder is mounted on the leg portion of the bed frame. The first electric cylinder drives the head portion of the bed frame, and the second electric cylinder drives the leg portion of the bed frame. The first electric cylinder and the second electric cylinder cooperate to control an inclined angle of the electric bed, and to lift or lower the electric bed horizontally.
